[Farm Lady]

Hi everyone. I can't seem to figure out the cooperative quests. How do I buy the products I need from friends/neighbors? People are selling me the products I put the yellow notes on. When I go to a neighbor's farm w/ the blue light on it says "you cannot buy this product because you don't have any cooperative requests needing it." So 1) how do I buy what I need and 2) how can I sell them items they need that I have.

Thanks for your help!!
